(1) Remove nut, lockwasher, washer, and
wire 18 from transmission temperature
(2) Remove transmission temperature
switch from reducer.
(3) Hang transmission temperature switch
in pan of water. Do not let switch make
contact with pan.
(4) Place a thermometer in water.
(5) Put heat to pan of water and stir water
for consistent temperature of 200°F
(93.3°C). Allow water temperature to
stabilize for 15 minutes.
Do not allow fingers or skin to contact
hot water or hot parts. Serious burns
to personnel could result.
(6) Set multimeter to ohms.
(7) Connect multimeter positive lead (+) to
stud of transmission temperature
(8) Connect multimeter negative lead () to
hex or large threads of transmission
(a) If 115 to 140 ohms are not
measured, replace transmission
temperature switch (Para 8-16).
(b) If 115 to 140 ohms are measured,
install transmission temperature
switch (Para 8-16) and go to
Step 5 of this fault.
(1) Remove four screws and panel.
(2) Connect multimeter positive lead (+) to
wire 18 at high transmission
temperature indicator terminal.
(3) Using a known good jumper wire,
connect multimeter negative lead () to
wire 18 at transmission temperature
(a) If continuity is not present, replace
wire 18 (Para 8-48).
(b) If continuity is present, go to Step 6
of this fault.
